Description

The Jonsbo H4 addresses the growing demand for internal connectivity in modern PC builds. As users integrate more RGB controllers, liquid cooling systems, and specialized monitoring hardware, motherboard USB 2.0 headers are often exhausted. This compact hub effectively multiplies a single internal header into four, ensuring stable data transmission and power delivery for all your internal components.


- PC Enthusiasts building custom water-cooled loops requiring multiple pump and sensor connections.
- RGB lighting enthusiasts managing multiple proprietary controller boxes.
- System builders utilizing cases with extensive front-panel or internal peripheral connectivity.
- Users upgrading older motherboards that lack sufficient internal USB headers.
- IT professionals and modders requiring organized cable management for internal USB devices.

- Model: H4
- Dimensions: 105mm (W) x 52mm (D) x 17mm (H)
- Material: ABS Plastic
- Cable Length: 500mm
- Power Input: SATA
- Interface: 1-to-4 USB 2.0
- Wiring: 24/28AWG Tinned Copper
- Rated Voltage: 5V

Installation is straightforward thanks to the integrated magnetic base, which allows the hub to be secured anywhere on a steel PC chassis. The 500mm cable length provides ample reach for routing behind the motherboard tray, promoting a clean, clutter-free aesthetic. By utilizing a dedicated SATA power connection, the H4 ensures that connected devices receive consistent voltage, preventing the data drops or recognition issues often associated with passive hubs.

Compared to standard passive USB splitters, the Jonsbo H4 offers superior reliability due to its active SATA power delivery. While basic splitters rely solely on the motherboard's 5V rail—which can be easily overloaded—the H4 draws power directly from the power supply unit. This makes it a safer and more robust choice for powering multiple high-draw internal devices simultaneously.

- Does the Jonsbo H4 require drivers? No, it is a plug-and-play device that is automatically recognized by all major operating systems.
- Can I use this for high-speed data transfer? No, this hub is specifically designed for USB 2.0 internal peripherals and is not intended for high-speed data storage devices.
- Is the magnetic base safe for hard drives? Yes, the magnets are shielded and designed for PC chassis mounting, posing no risk to modern SSDs or HDDs.
- Does it support RGB controllers? Yes, it is fully compatible with most internal USB-based RGB and fan controllers.
- What is the warranty period? The Jonsbo H4 comes with a one-year manufacturer warranty.
